hard clay to soft clay

hi
i was looking for a script to turn hard clay into soft clay but i coulldnt find one which worked well enough. i thought this should be an easy script to write as it only needs to withdraw items and use them with eachother then deposit. could someone try to devolope a script to do this as i have alot of clay to soften.
thanks hope someone can help

 

where you suggest it do this... edgeville?
